九人（Y. Taniguchi、H. Suto、T. Hasekawa、K. Wakamatsu、M. Tanaka、K. Iwasawa、F. Sato、Y. Sofue 和 K. Ogura）被委托进行光学、红外和射电区域中不同波长的天文观测。目标是 1）星际介质（Suto、Tanaka 和 Ojura）2）星系（Taniguchi、岩泽和Sfue），3）星系团（长谷川，Wkamatsu）。他们活动的国家或地区是北半球的莫纳肯（JCMT和UKIRT）、美国格林班克和德国波恩，以及智利和南非的托洛洛山、拉西拉山。1）Suto对J、H和K波段的15个恒星形成区域进行了红外成像。在红外源 IRAS 11072-7727 周围检测到了一个显着的星云复合体。小仓利用SEST（瑞典-ESO）望远镜对他自己发现的赫比格-哈罗天体HH135/136进行了观测，其CO谱线为1.3和1.4毫米。在 12CO(J=2-1) 发射线中 1.3mm 处检测到高速分子流出，而在 13CO(J=2-1) 中发现了包围两个 HH 天体的致密分子核心。佐藤利用美国 NRAO Greenbank 43m 射电望远镜在波长 21cm 处对具有中性氢的仙王座-仙后座复合体区域进行了广泛的观测。在巡天中，他勾画出了包围该复合体的中性氢云，以及位于银经110°、银纬3°处的直径为10°的壳层结构。2)谷口发现星爆星系中核周云的温度明显高于我们星系中正常分子云的温度。田中检测到了较宽宽度的H2分子线Seyfert/cD星系NGC1275，光谱分辨率为30 km/s。岩泽用CTIO 1.5m望远镜获得了17个星系光学区的光谱。他在 IRAS18325-5926 中发现了显示典型 Seyfert 2 的光谱，根据 Ginga 的 X 射线观测，将其指定为 Seyfert 1。他还在Tololo 0109-38的Fell lambda 4570处探测到了一个凸起，以及一个与Mkn603相关的蓝色致密矮星系。Sofue尝试使用德国波恩100 m射电望远镜探测到三个类星体或红移为2到3的相关天体的CO吸收线，但未能以足够的信噪比探测到它。3）长谷川进行了衰退测量使用南非 1.9m 望远镜的 RPCS 低分辨率光谱仪测量蛇夫座星系团中 50 个星系的速度。他发现了新的星系团。结合自己和同事之前发现的星系团，他得出结论，这些星系团形成了超星系团，超星系团与我们之间存在着巨大的空隙。若松利用智利CTIO 1.5m望远镜的卡塞格伦光谱仪对上述区域进行了广泛的光谱巡天。上述向武仙座星系团延伸的超星系团呈现出100 Mpc范围的“墙”结构。因此，该计划开展了多个领域的研究，涵盖星际介质、星系活动和星系团结构。有多篇高水平论文已发表或正在撰写中。如果没有位于世界上绝佳地点的望远镜，这些成功就不可能实现。本次研究计划已实现大部分计划。较少的

Nine persons ( Y. Taniguchi, H. Suto, T. Hasegawa, K. Wakamatsu, M. Tanaka, K. Iwasawa, F. Sato, Y. Sofue, and K. Ogura ) were delegated for astronomical observations with various wavelengths in the optical, infrared and radio regions.The objectives are 1) interstellar medium ( Suto, Tanaka, and Ojura ) 2) galaxies ( Taniguchi, Iwasawa, and Sfue ), and 3) clusters of falaxies ( Hasegawa, Wkamatsu ).The countries or areas where their activities were devoted are Mauna Ken (JCMT and UKIRT), Greenbank, USA, and Bonn, Germany, in the northern hemisphere and Cerro Tololo, La Silla in Chile and South Africa.1)Suto made infrared imaging for 15 star-forming regions at J, H, and K bands. A remarkable complex of nebulosities was detected around infrared source IRAS 11072-7727. Ogura carried out an observation of Herbig-Haro objects HH135/136, which had been discovered by himself, with CO lines at 1.3 and 1.4 mm at SEST (Swedish-ESO) telescope. A high-velocity molecular outflow was detected in the … More 12CO(J=2-1) emission line at 1.3mm, while a dense molecular core encompassing thetwo HH objects was revealed in the 13CO(J=2-1).Sato made an extensive survey of a Cepheus-Cassiopeia complex region with neutral hydrogen at a wavelength of 21cm with NRAO Greenbank 43m radio telescope, USA. In the survey, he delineated the neutral hydrogen cloud enveloping the complex, and a shell structure with a diameter of 10ﾟ degrees locating at a galactic longitude 110ﾟ and a galactic latitude 3ﾟ .2)Taniguchi found that temperature of circumnuclear clouds in the star-burst galaxies is significantly higher than that of normal molecular clouds in our galaxies.Tanaka detected a broad width of H2 molecular line for a Seyfert/cD galaxy, NGC1275 with a spectral resolution of 30 km/s.Iwasawa obtained spectra in the optical regions of 17 galaxies with CTIO 1.5m telescope. He found a spectrum exhibiting the typical Seyfert 2 in IRAS18325-5926, which was designated to Seyfert 1 from the X-ray observations by Ginga. He also detected a bump at Fell lambda 4570 in Tololo 0109-38, and a blue compact dwarf galaxy associated with Mkn603.Sofue tried to detect the CO absorption line toward three quasars or related objects with the redshifts of 2 to 3, using the Bonn 100 m radio telescope in Germany, but failed to detect it with sufficient signal-to-noise ratios.3)Hasegawa made a measurement of recession velocities for 50 galaxies in the cluster of galaxies in Ophiuchi constellation using RPCS low-resolution spectrometer at 1.9m telescope in South Africa. He discovered new clusters of galaxies. Combining the clusters of galaxies previously discovered by himself and his colleagues, he concluded that these clusters of galaxies form a supercluster of galaxies, and there lies a huge void between the supercluster and us.Wakamatsu carried out an extensive spectroscopic survey for the above region with the Cassegrain spectrometer at CTIO 1.5m telescope, Chile. The above super-cluster extending toward Hercules cluster of galaxies shows 'Wall' structure with an extent of 100 Mpc.Thus, a various field of researches were carried out in this program, covering interstellar medium, activities in the galaxies, and structures of the clusters of galaxies. A number of papers with high levels were published or are in preparation. Without the access to the telescopes located at the excellent sites in the world, these success could not be attained. Most of the planned schedules have been achieved in this research program. Less
